Application tiled February 16, 1885.

which similar letters of reference indicate corresponding parts in all the iigures.4

Figurel is a cross-sectional elevation ofthe button shown and described in my Letters Patent No. 298,303. Eig. 2 is a side View of my improved collar-button. Fig. 3-is a cross-sectional View of the same on the line xm, Fig. 2.

The button A (shown in Fig. 1) has a hollow stem, B, and head C, all made in one piece With the base-plate D.

rounded head and to prevent the edges of the head from cutting into the skin in case the (No model.)

button is tilted and laid over against thearrn.`

or wrist with the shirt-sleeve.

I am aware that busk-fastenings and metal rivets have been made by forming a hollow metal shank or stem, and then flattening down or upsetting the end ofthe saine to form ahead,

which head, however, is fiat, and has its sharp edges projecting laterally from the stem, which` i I desire to avoid for the reasons stated.

I do not form the head by upsetting Or iiattening the end of the stem; but the hollow head is first formed by contracting the stem, f and then the top and bottom of the head are 1 pressed together.V i I-Iavingthus described myinvention, Iclaim as new and desire to secure by Letters Patent- As an improved article of manufacture, a collar-button having a hollow stem formed on abase, a head on the stem, the top and bottoni` .y

layers of the head being pressed together to be in contact, and the edges of the head being bent down to form a curved top surface for` the as herein shown and described.
